When butane, CH3CH2CH2CH3 and bromine gas, Br2 is exposed to sunlight, monobrominated product are produced. The reaction equation is given below: (i) State the type of reaction (ii) What is the function of the sunlight in the reaction? (iii) Draw the structure of monosubstituted products, A and B. Label the major product.
Reactions of Ethers
Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.
Epoxides
Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.
Williamson Ether Synthesis
An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.
When butane, CH3CH2CH2CH3 and bromine gas, Br2 is exposed to sunlight, monobrominated product are produced. The reaction equation is given below:
(i) State the type of reaction
(ii) What is the function of the sunlight in the reaction?
(iii) Draw the structure of monosubstituted products, A and B. Label the major product.
(iv) Draw the propagation steps in the mechanism for the formation of the major product.
